Description
Technical field:
The utility model belongs to mechanical field, is specifically related to be used for the employed synthesis reactor of strong heat release isothermal reaction of chemical industry, petrochemical industry and other engineering, the synthetic tower of especially suitable methyl alcohol building-up reactions.
Background technology:
Present known strong heat release isothermal reaction, more use shell and tube-type reactor.Its basic structure is: two blocks of stationary tubesheets of upper and lower settings in reactor shell, and reaction tubes and housing weld with tube sheet simultaneously; Catalyzer places in the reaction tubes, relies on the boiling of the outer water of pipe (or liquid) to remove reaction heat.This kind structure is owing to exist thermal expansion force between reaction tubes and housing, the time regular meeting's generating pipe plate and housing weld seam by the phenomenon of drawing crack, serious threat is to production and personnel safety.
In order to reduce the destruction of thermal expansion force to equipment, the tube length of reaction tube of shell and tube-type reactor is shorter mostly, generally is controlled at 6～7m, and requires the linear expansivity of reaction tubes and shell material close.The tube and shell type methanol synthesis converter reaction tubes material that domestic methyl alcohol, synthetic ammonia industry are introduced the technology manufacturing of German LURGI is 2205 (duplex stainless steels), and shell material is 13MnNiMoNbR.So not only make the manufacturing cost of equipment high, the equipment of identical production capacity is because the restricted volume of tube length of reaction tube is huge, and influences the raising of transformation efficiency in the production process, reduced energy-saving effect.
The utility model content:
The purpose of this utility model is exactly to provide a kind of floating head type isothermal reaction methanol synthesis reactor of high efficiency, low cost in order to address the above problem, and it has overcome tube sheet and housing weld seam easily by the defective of drawing crack.
A kind of floating head type isothermal reaction methanol synthesis reactor described in the utility model, mainly comprise the low pressure body skin, the body skin lower cover, the high-temperature gas fairlead, the high pressure upper tube box, end socket in the high pressure, upper tubesheet, lower tubesheet, the reaction tubes of catalyzer is equipped with in inside, gas distributor and gas inlet tube, its mesohigh upper tube box, low pressure body skin and body skin lower cover are welded as a whole, gas inlet tube passes the high pressure upper tube box and enters its inside, at the gas feed tube end gas distributor is installed, upper tubesheet and lower tubesheet are installed in both sides up and down, low pressure body skin inside respectively, many reaction tubess are installed between upper tubesheet and the lower tubesheet, end socket is installed on the lower tubesheet in the high pressure, the high-temperature gas fairlead is welded on high pressure interior end socket bottom and extends the body skin lower cover, it is characterized in that: described upper tubesheet is fixedlyed connected with the low pressure body skin, running fit between lower tubesheet and the low pressure body skin, be equivalent to like this end socket in lower tubesheet and the high pressure is formed " floating head ", this floating head can move freely by the relatively low pressure body skin.
Adopt running fit between high-temperature gas fairlead and the body skin lower cover, can relatively move between the two, and seal with lock packing.The extension of high-temperature gas fairlead is equipped with expansion joint.
In high pressure upper tube box outside the discharging hand hole that is communicated with inside is housed, is convenient for changing the catalyzer in the high pressure upper tube box.
The utlity model has following advantage:
(1) because refrigerant (water) can triflux (heat transfer) reaction tubes outside, so fabulous temp effect such as grade is arranged.
(2) catalyzer or the protective material of upper tube box filling can draw off independent replacing by three hand holes that are provided with are all or part of.
(3) owing to do not fixedly connected between reaction tubes and housing, eliminated thermal expansion force, so there is not the potential safety hazard of tube sheet and the drawing crack of housing weld seam; Reaction tubes and shell material need not to have saved a large amount of noble metals with import or homemade duplex stainless steel, have reduced equipment manufacturing cost; The length of reaction tubes can extend according to the needs of reaction kinetics, thereby transformation efficiency is improved, and the device diameters of identical production capacity reduces.The difficult problem of large-scale reactor transportation is alleviated.
(4) the utility model reaction tubes can freely stretch in housing, " energy-saving and emission-reduction " technological transformation of the methyl alcohol of domestic low middling scale preferably, synthetic ammonia installation.
